Ok, here's how LD50 works. Greater potency in mice = greater potency in humans. HOWEVER, the exact LEVEL of toxicity is what does not correspond to humans. For instance, an LD50 0.30 in mice is more toxic in BOTH humans and mice, than an LD50 0.90. BUT, 0.30 and 0.90 are not the actual potency in humans.LD50 are ok for mice but I am thinking,what is the most dangerous to man.
Also,in terms of aggression......
Which one would you say is an OBT and which a rosea for instance
or are they both H.gigas....You know what I mean

The relationship between LD50 values stays the same: more potent = more potent. The mathematical mg/kg rating is almost always far more potent in humans than in mice. We just use them as a comparison test bed. If the LD50 in mice is 50.00 mg/kg, it's not going to be significantly toxic for humans until dosage becomes gigantic. If the LD50 in mice is 0.30, it definitely will be highly toxic in humans also.
Generally, LD50 in mice indicates far LESS toxicity than actually is the case for people: we are MORE susceptible than the LD50 values indicate.
LD50 IS VERY important in estimating approximate toxicity to humans. That chart you were given is entirely relevant and you should take it seriously.
